ATI'JFOIWIATIC LIGHTING- DEVICE.

Application filed September 12, 1822. Serial No. 587,814.

To all whom it may concern.

Be it known that T, JACOB Hrnn, a citizen of the United States, residing at Seattle, in the county of King and State of VVashington, have invented certain new and useful. Improvements in an Automatic Lighting Device, of which the following is a. specification.

This invention relates to lighting devices, and especially to an improved automatic lighting device for a bake-oven.

One object of this invention is to provide a comparatively simple and thoroughly effective device for lighting the interior of a bake-oven or other chamber which is provided with a door or closure.

Another object of the invention is to provide a device of this character which is at tachable to most every kind of oven or chamher in such manner as to effectively light the latter.

A further object is to provide, in combination with the lighting means, an automatic means for moving the lamp alternately into and out of the path of the door or closure, so that the latter may be closed and opened without interference, and so that the lamp is in front of the oven when the door is open.

Other objects or advantages will be pointed out or implied in the following details of construction in connection with the ac companying drawings in which:

Fig. 1 is a front elevation of a part of a stove comprising two ovens, the upper oven being closed, and the lower oven being open.

Fig. 2 is a vertical sectional view along the line 22 of Fig. 1.

Fig. 3 is a diagrammatic view of the electric circuit which includes the lamps for lighting the ovens.

Referring to these drawings in detail in which similar reference characters correspond with similar parts throughout the several views, and in which each oven (0) may be of any ordinary or improved design, but which in the present instance includes a main or outer door (D) and an inner door (d), these doors being hinged to the stove body or front (S) and pivotally connected to one another through the medium of a link or links (Zi): The invention consists in the combination of these parts or their equivalent with the structure which will now be described as follows:

One of the hinges of the upper door (D) is shown at (h), and it should be understood that a similar hinge is provided for the part of the door and body (S) which is broken away at the right-hand side of Fig. l. The door (D) swings down from the closed position, shown at the upper oven (0) to the open position, shown at the lower oven (0), in Figs. 1 and 2. Latches (la) are provided for the upper and lower doors (D), and handles (ha) are provided. The structure defined in theforegoing has been known prior to the present invention, and is not claimed separate from the structure which will now be described as follows:

The body (S) is apertured at 5, and bearings 6 are secured in these apertures 55. Tubular arms 7 are loosely threaded or otherwise pivot-ally secured in the bearings 6, and lampsS are secured on the free ends of the arms 7 and provided with reflectors 9.

Electric conductors 10 extend from the lamps 8, through the bearings 6, and are connected electrically with conductors 11.- The latter conductors connect with or include a battery 12 and switches 13. The switches 13 may be closed by any appropriate means, springs 14 being here indicated for this purpose, and when either door (D) is open, its switch 13 is closed by the corresponding spring 14:; but when either door is closed its switch 13 is opened by means of an arm or extension 15 of the door (D), this arm 15 pressing againstv a plunger of the spring and holding it in the open position so long as the door is closed: However, when either door is opened, its switch 13 is released and permitted to be closed by its spring 14, so that the batterycircuit is closed, and its lamp 8 is thereby lighted.

For the purpose of swinging each arm 7 up and down or to and from a position in front of the oven, a link 16 is pivoted at 17 to the arm 15, and pivoted at 18 to the lateral extension of the arm 7. Therefore, when either door is open, its lamp 8 is in the lowermost position or in front of the open oven, but by the operation of closing the door the links 16 swing the arm 7 and its light 8 up out of the path of the door.

It will be seen, therefore, that th operalamp alte1'11atelyfro1n thenseful position to the out-oit-theway position.

It is not intended to limit this invention to the exact details of construction here shown and described, but changes maybe made Within the scope of th inventive ideas as implied and claimed. 7 7

What I claim as my invention is:

A 1. The. combination with an oven anda hinged door for opening and closing the oven, of an electric circuit including a lamp, an arm carrying said lamp and a portion of said electric circuit, said arm being p ivo t ally mounted position to move the lamp into and out of the position in front of the oven, and means including a link for connecting said armtoi said door so as eilect .moyeniei1tofsaidarin and itslamp when the door i s opened and closed, means also being aiitoinatipally operable for opening and closing" said electric circuit,

2. The eastwards with a eiiaataand its closure, of an electric circuit including a lamp and a switch, a tubular arm carryin said lamp, a bearing in which said tu ular arm is pivotally mounted in such position that the arm can move its lamp to and from a position in front of the chamber, a part of said electric circuit extending through said bearing; and tubular arm and being connected to said lamp, and means automatically operable by said closure, for simultaneously operating said switch and effecting the pivoted movement of said arm in said bearing.

a 3. The structure defined by claim 2. said means including an extension of said closure, and a link pivotally connected to sa d extension and to said tubular arm, said switch being in the path of said extension and thus being operable by the latter or automatically opening the switch by the operation of moving the closure to the posi tion forclosing the chamber.

In testimony whereof I afiix my signature.
